This application provides a motor controller for an electric vehicle. The motor controller includes a control circuit and an inverter circuit. The control circuit is configured to: in response to that the drive motor rotates with a pair of wheels of the electric vehicle, control a switch module to connect a center tap of the multiphase winding to the other end of the power battery, and control the inverter circuit to adjust a voltage at both ends of the bus capacitor. The bridge arms of the inverter circuit of the motor controller provided in this application and the winding of the drive motor form a voltage conversion circuit to adjust the voltage at both ends of the bus capacitor, to improve power performance and vehicle endurance of the electric vehicle.
